Reduced ATP

Equipment has been factory–tested for FCC compliance. If

license–governing bodies require documentation

supporting SITE compliance with regulations, a full ATP

may be necessary. Perform the Reduced ATP only if

reports for the specific BTS site are NOT required.

NOTE

After downloading the proper operational software to the BTS, the

Cellular Field Engineer (CFE) must perform these procedures (minimal

recommendation):

1 Verify the TX/RX paths by performing TX Calibration, TX Audit

and FER tests.

2 Retrieve Calibration Data required for normal site operation.

Should failures occur while performing the specified tests, refer to the

Basic Troubleshooting section of this manual for help in determining the

failure point. Once the point of failure has been identified and corrected,

refer to the BTS Optimization and ATP Test Matrix section (Table B-1)

to determine the applicable test that must be performed.

In the unlikely event that the BTS passes these tests but has a forward

link problem during normal operation, the CFE should then perform the

additional TX tests for troubleshooting: TX spectral mask, TX rho, and

TX code domain.

Refer to Chapter 3 for detailed information on test set

connections for calibrating equipment, cables and other test

set components, if required.

NOTE

Customer requirements determine which ATP tests to are to be

performed and the field engineer selects the appropriate ATP tests to run.

The tests can be run individually or as one of the following groups:

 All TX: TX tests verify the performance of the BTS transmit line up.

These include the GLI2, MCC, BBX, and CIO cards, the LPAs and

passive components including splitters, combiners, bandpass filter,

and RF cables.

 All RX: RX tests verify the performance of the BTS receiver line up.

These includes the MPC (for starter frames), EMPC (for expansion

frames), CIO, BBX, MCC, and GLI2 cards and the passive

components including RX filter (starter frame only), and RF cables.

 All TX/RX: Executes all the TX and RX tests.
